STEINERT PLASMAX®️ | LIBS

The newly developed STEINERT PLASMAX | LIBS promises to sort three products in one run, undertake a novel multi-spot analysis and deliver purity levels of more than 95%.

Replete with numerous innovations – the STEINERT PLASMAX | LIBS is the solution for high-purity separation of aluminium alloys and can handle large volumes. Delivering purity levels in excess of 95%, the new LIBS system achieves high quality levels, enabling the sorted product to be fed straight back into the production process.

Volume sorting with maximum precision

With a processing capacity of 3-6 t/h and three material discharges at the same time – the STEINERT PLASMAX | LIBS makes what is probably the most efficient processing of high-grade aluminium scrap possible and therefore answers the needs in the recycling market.

The new sorting system brings together several technological innovations and combines them on the tried-and-tested STEINERT KSS platform – a symbiosis, promising maximum quality and reliability. The compact design also makes the sorting system very easy to integrate into existing systems.

A new approach to sorting aluminium alloys

The material starts to be processed as soon as it is placed on the new feed system. A specially developed multi-stage feeder ensures that the conveyor belt is covered optimally.

Next up is 3D detection and an ultra-precise in-flight detection: in other words, detection immediately after the material has left the belt. Due to the inertia, the material passes through the scan area in a stable drop parabola. The innovative multi-spot analysis is optimally oriented to the material and ensures ideal detection with multiple laser measurement points.

The plasma produced when the laser beam hits the aluminium is analysed using AI and, a moment later, separated into one of the three discharges by a targeted compressed-air pressure pulse.

STEINERT UMP Multipol

New quality levels for ferrous concentrates: the STEINERT UMP Multipol

The new UMP Multipol permanent magnet from STEINERT features alternating magnetic poles, enabling it to set new standards in improving the quality of ferrous concentrates and effectively removing impurities.

The STEINERT UMP Multipol provides an advanced solution for enriching and cleaning ferrous concentrates. By changing the magnetic polarity several times, the material is turned over multiple times beneath the conveyor belt, removing non-magnetic impurities effectively. This greatly improves the quality of the ferrous fractions. Furthermore, copper losses in ferrous concentrates can be significantly reduced in Waste Electrical and Electronic Equipment (WEEE) applications.

The overhead suspension magnet with permanent magnets lifts ferromagnetic pieces of scrap (predominantly iron) out of the material flow against gravity. The innovative process of changing polarity turns the attracted pieces of iron over several times, releasing non-magnetic impurities. At the end of the conveyor belt, the cleaned ferrous material is discharged separately. Using permanent magnets ensures that only minimal levels of energy are required, making the STEINERT UMP Multipol a very cost-effective solution.

UniSort Finealyse®+

UniSort Finealyse+ is a higher-performing version of its established UniSort Finealyse sensor sorting system.

This new machine was developed especially for the challenges experienced when processing plastic flakes and granulates as well as when sorting metal granulates with grain sizes ranging from 2 to 30 mm.

The diverse potential uses for this product range from sorting plastic flakes to metal applications. UniSort Finealyse+ reliably removes incorrect colours and unwanted plastics from plastic flakes. It is also well suited to colour sorting of non-ferrous metals in addition to removing unwanted plastics from e-scrap. This all results in high flexibility and product purity with minimal material losses.

The sorting unit is available with a high resolution NIR (near-infrared) camera, with a highly selective colour detection unit or with NIR and colour sensor combination with sensor fusion technology. The sensor combination including a colour camera, allows additional characteristic properties that can be identified and mapped at the same point, ensuring even more stable detection.

The material is passed through a feed and dispensing device and lands on the integrated conveyor belt. The feed material is accelerated by a high-speed belt and pressed onto the belt using the active object control (AOC) system developed by us at STEINERT – and is held in a stable position even after leaving the belt. This relatively elaborate but effective stabilisation helps to steady even the smallest objects on the belt in a controlled manner and keep them in the calculated position on the parabolic trajectory after leaving the belt.

Whilst the sortable material flows through the detection area, the corresponding sensor detects the type or colour as necessary and the position on the conveyor belt. The controller then activates the correct nozzles at precisely the right time and position. The nozzle bar is arranged above the material flow and shoots from top to bottom. Detected foreign particles are then extracted exactly and with low material loss by a targeted blast of compressed air. The sorted fractions can be transported to the next processing stage on material discharge conveyors.

For the best possible sorting at all times, UniSort Finealyse + also provides an automatic white balance for calibration purposes and a split variant for simultaneously running several sorting processes on one machine. The split function allows several material flows to be sorted at the same time or for the sorted product to be subsequently cleaned in parallel on one machine.
